Is Global Warming becoming unstoppable?

This story is very concerning. It seems that households and kitchens in particular are a very large source of methane leakage. This has health implications as well as being a large but unacknowledged contributor to greenhouse gas emissions accelerating global heating.

Leaking methane from natural gas-burning stove tops is releasing the greenhouse-gas equivalent of hundreds of thousands of cars, and cooking on gas stovetops is posing a risk to health, according to new research.

Key points:​

  • The majority of methane is released from gas cookers while not in use
  • Nitrous oxides, fine particulate matter released during cooking pose a respiratory risk, especially to children
  • Monitoring of methane emissions is lacking right through the supply chain, according to the Climate Council
In findings that have taken researchers by surprise, more than three quarters of methane emissions from stovetops were leaking into houses while the appliances were not in use.

They're the results from a study published today in the journal Environmental Science and Technology, which looked at natural-gas emissions from stovetops in households in the United States.

The researchers are hoping to replicate the study in Australia, and believe the US results are largely comparable with the situation here.
"COVID-willing, we hope to sample in Australia over the next year or two, probably in 2023," said study co-author, Professor Robert Jackson from Stanford University.

"Our biggest surprise was that most of the methane we measured leaked to the air while the stoves were off."
While the rate of methane leakage was higher while the stoves were in use, the amount of time spent not in use meant the overall volume of methane leaked was greatest during this time.

Previous studies have found methane emissions from gas stovetops to be lower than this one, but they only measured emissions when the stoves were on, Professor Jackson said.

 
It was provided in the link!
That was a fabrication (in simple terms you posted a lie) - find the original German version and I will translate it for you.
it’s rather self evident and explanatory!
Indeed it is. For over two hundred years the first world overload our planet with CO2 but you now want to blame the most populous nation that still has half the per capita carbon footprint that you have.

you only claim it’s a lie as it doesn’t suit your narrative! It’s a well documented quote and interviews!
German is my native tongue so I can read it thx

Lol!
Is that all you have
There total omission rates are skyrocketing and are building hundreds of new coal power stations yet its Australian cows!

yet we need to destroy the land to build these point wind mills and solar panels!

to continue to believe this crap is just how gullible and stupid society has become!

ifnthere was any truth if it was to save the planet and renewables actually were some what useful China would not be building coal power stations for staters it would be bulldog renewables!
It’s none of that!

there has been a few proposals over the years to generate electricity look up nikola Tesla and his theory of kinetic energy!!

any muppet that peddles renewables thinking that work has the iq or a house plant
 
you only claim it’s a lie as it doesn’t suit your narrative! It’s a well documented quote and interviews!
It's a proven fabrication - as my earlier link showed - so the lie sits with you.
There total omission rates are skyrocketing
Sorry... that's not true either. Their emissions have increased due mostly to western nations offshoring production, and there is no counter to this fact.
if there was any truth if it was to save the planet and renewables actually were some what useful China would not be building coal power stations for staters it would be bulldog renewables!
Just to reiterate how little you know, in 2020 China led the world in renewable capacity added, accounting for nearly half of all installations. China added nearly 117 GW, bringing online more renewable capacity in 2020 than the entire world did in 2013 and almost doubling its additions from 2019.

Most people believe the opposite is true.

what link?
all the links i post seem to go totally over your head and you clearly struggle to under stand them! only to parrot the same dribble as the rabble such as the ABC produce
very selective leftist journalism

why are they building all those new coal fired power stations! there omissions are already nearly 1/3 rd of the worlds total
all those renewables you claim they are building must have little confidence in them!

yet Australian farting cows are the issue?
tell me again how old Vlad lenin didnt use propaganda despite calling his leftist followers useful idiots?


those globalist leaches want every one poor and taxed to the hilt whilst they want there tax free off shore banking and be excempt from paying any form of taxers! and you parrot the exact words for them
 
Look at the Antarctic this year.
Not good. (Also shows Arctic).

Also BOM annouced hottest January night temperatures for Melbourne on record- due to the weird weather we were having.
 
The ecology of Antarctica is changing in literally a decade. Global heating is accelerating.

Flourishing plants show warming Antarctica undergoing ‘major change’

Dramatic spread of native plants over past decade is evidence of accelerating shifts in fragile polar ecosystem, study finds

Antarctica’s two native flowering plants are spreading rapidly as temperatures warm, according to the first study to show changes in fragile polar ecosystems have accelerated in the past decade.

The increase in plants since 2009 has been greater than the previous 50 years combined, coinciding with rapidly rising air temperatures and a reduction in the number of fur seals, according to researchers working on Signy Island in the South Orkney Islands.

Populations of Antarctic hairgrass (Deschampsia antarctica) and Antarctic pearlwort (Colobanthus quitensis) have been studied by scientists on the island since 1960. Research found hairgrass spread five times faster between 2009 and 2018 than between 1960 and 2009. For pearlwort, the increase was almost ten times more, according to the paper.

In the past decade, summer warming has increased from +0.02C to +0.27C each year, despite strong cooling recorded in 2012.

 
Article on the state of play with renewables, the final two sentences sum it up.

Whitworth said: “For China, the energy transition is a golden opportunity to develop key industries and technologies while improving its green credentials. Accelerating efforts to tackle its own emissions while supporting global decarbonisation sounds like an irresistible proposition.

“For the western economies, responses are more wide-ranging – tariffs, local content policies, tax breaks, collaboration, technical innovation, etc. Competition from all sides is intense, which should bring benefits to the trajectory of global decarbonisation.
 
A summer of broken heat records in WA. A reminder that global heating is not going away.


Fingerprint of climate change

Unfortunately, climate science indicates this is just the start.


H=485&cropW=862&xPos=0&yPos=0&width=862&height=485.jpg

Rainfall has declined significantly in the last 50 years over WA's south-west.
While it can be difficult for scientists to directly attribute extreme weather events to climate change, climate scientist Andrew King said Perth's summer clearly bore the fingerprint of global warming.

"Given the background trends and previous work looking at heatwaves and their links to climate change in different parts of Australia, and our understanding of how the climate system works, we can be quite confident that climate change has exacerbated the heat and Perth the summer," Dr King said.

He said there would still be cooler summers in future, but climate change had loaded the dice to make hot years more common.

"Because we've got such a clear trend in temperatures across the whole of Australia, including in Western Australia, it's just quite easy to break records these days," he said.
"I guess an analogy to that is you can think of like COVID cases.

"If you've got an outbreak occurring, you can have record numbers of cases each day, day after day, when you've got a strong trend in case numbers.

"In a way, temperature trends are a bit like that, when you've got a very clear trend, it's very easy to break records so you break them more frequently."
 
Rainfall has declined significantly in the last 50 years over WA's south-west.
An interesting thing about WA is that the decline hasn't occurred in manner that correlates to anything obvious but rather, has occurred as distinct "steps" downward in runoff.

It's as though someone simply flicked a switch and said that's it, we're going to level 1 climate change as of midnight tonight and that's it, done. Then came back later and turned it up to level 2.

Far less extreme but the same "sudden step" pattern exists in Tasmania also. Get a bar chart of runoff records and it's very clear that there was no gradual decline, it's a sudden step change.

Politics around climate change and solutions to reducing emissions etc aside, there's some interesting science there in terms of what's going on to cause that response since there isn't a direct correlation with something obvious. Not sure about WA but Tas has done quite a bit of research at the state level looking for an explanation. :2twocents

Going off at a bit of a tangent to the discussion here, but related... We are about to buy a property here in WA. First order of priority is contingency planning should the power go down or is insufficient.

It's actually quite a complex problem for someone who has never considered all the facets which may eventually come into play.

But let's just say that Mrs and I are learning how to make fire by rubbing sticks together... just in case :p
 
In case anyone missed it :cautious: Climate Change has well and truly arrived in Australia. The flood events across the East Coast have all the fingerprints of the extreme weather patterns that a warming climate will produce. So where to from here ?

 
As you have told us repeatedly, one off events or even one season events are weather, not climate change.

Weather sites forecast La Nina and it arrived, so all good so far.

Why are we having floods, because over the past few decades many more houses have been built on flood plains.

Why higher then previously, often times, it is because the overflow areas up river that used to hold the water for a week or more no longer exist, they have been filled and have houses on them.

Just in my area, along the banks of the Hunter river, which is a dangerous river for flooding, there are dozens of houses which have been built right next to the river.

The Councils have allowed people to build flood island for their houses, they have created mounds up to 10m high and 100m long and there can be 6 or 8 in a row.

These have become a virtual levee bank preventing the water from spilling out over the farmlands as it has done so for centuries.

By changing the flow of the river and directing all of the water back into the river it will result in higher floods in Raymond Terrace.

When it does, someone will cry climate change, old hands will say "We told you so"

You have missed the real point about the difference between weather and climate.
Climate is a pattern of weather events and that pattern is near unequivocal.
The planet is warming. Warmer atmospheres contain more energy. More energy leads to greater intensity of weather events. This does not necessarily mean we will get more cyclones, for example, but it does mean that on average their intensity is greater over time.
Your anecdote is irrelevant to global climate. Some parts of the globe have cooled in the past 100 years, and even some glaciers have grown in size. But the overall pattern is the very opposite.
 
Macca you overlook the fact that the volume and intensity of rainfall has trashed all records. But on a practical basis flood insurance is almost impossible in many areas. On top of that the insurance costs of natural disasters (even when companies have not insured whole areas) is raising insurance premiums around the country.

This isn't going away.

No one is suggesting that it is going away, as so often happens, activists have it back to front.

People who suggest that it has all happened are in fact saying, we need to learn to live with it and stop being like chicken little every time an unusual weather event happens.

I find it intriguing as to why CC lovers have this blind belief that ALL weather extremes have conveniently happened within the past 200 years so that we have had the opportunity to write them all down.

Anything outside of that is seen as catastrophic, yet, the Elders of the Sydney tribes have said before, that when Macquarie was shown around Windsor after the big flood, he was warned that a much bigger flood happened when they were young.

They indicated that the flood was up to 5 metres above the present debris in the trees.

Everyone needs to accept the fact that weather events are unpredictable, another example for you.

Brisbane Will get hit by a cyclone, when it does everyone will scream climate change, but in reality it did happen a few times before the white fellas got there.

I live quite a "green life" (not the Fake greens Party) but close to nature, it bugs me when I see all the litter that people toss into our parks and waterways.

It bugs me when people won't reuse, a lot of people recycle but that actually uses power to make the change, I mean reuse, as in a second hand item, so many useful things are thrown out in the Council clean ups.

So I am doing my bit locally in the hope that it helps but then I see photos of all the junk flowing out of Asian countries as they happily pump out pollution and everyone gives them a free ride.

Maybe we should be targeting the pollution we can see coming out of rivers and fouling the air, no one can argue about that so "there it is, clean it up".

Not just western countries but every country, with penalties if they don't do it

You are writing from the perspective of a person who confuses the past with the future.
Our planet has been a lot hotter and a lot colder, and wetter and drier in the distant past.
Our future climate will be dominated by the gases that warm our planet, and that trend will continue for many decades to come, irrespective of even extreme climate mitigation strategies.
When, as you do, write your own narrative and have no demonstrated understanding of climate science, it's easy to think that your local situation is the same most places. That's just not so. Furthermore, no amount of recycling will save us from additional warming, nor will the admirable cause of preventing pollution.

As with most things, the truth is somewhere in the middle.

Is the climate changing? The available data says yes, it is changing.

Have we experienced all extremes of weather that would occur with an unchanged climate since accurate records began? Almost certainly no, bearing in mind that for many areas the period of accurate recordkeeping is rather short.

Does recycling help? Well that depends what you're recycling and how you're recycling it. What can be said though is that of itself it's nowhere near a total solution despite having some benefits as such (noting that depending on what's being recycled, the primary benefit isn't necessarily about the climate since there's also other benefits from it).

All of this comes down to detail. Take plastic for example. Depending on circumstances it's anywhere between pure evil and the best thing invented thus far. Totally depends on the detail - what sort of plastic and what's being done with it. From a human safety perspective well as an electrical insulator and moulded structural material it sure as hell beats asbestos. As a food for birds and fish though well it's pure evil. Detail..... :2twocents
